IMPROVEMENT IN DRIVING MECHANISMS FOR RUBBlNG-ROLLERS 0F CONDENSER CARDING-ENGINES.

Specification forming part of Letters Patent N o. 212,102, dated February 11, 1879; application filed March 14, 1876.

To all whom it may concern:

i* Be it known that I, GEO. MALLISON, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and userul Improvement in Driving Mechanism for Rubbiug-Rollers of Oondenser Carding-Engnes, of which the following is a specification:

In the process of carding fiber which is to be used for spinning, three distinct machines are employed, the fibers bein g first fed into the first breaker-card, which delivers then in the form of a very loose rope, technicallyknown as a sliver or bat A number of these slivers or bats are fed into the second breakercard, from which the fibers are again delivered in the same form as from the first breaker, but in a more advanced state of manufacture. A number of these slivers or bats from the second breaker are now fed into the third machine of the series, called a condeuser, which discharges the fiber in the form of a number of narrow strips of a vcry loose texture, and about one inch wide.

ln order to give these tapes or stripssufficient cohesio for further stages of manufacture, they pass between two series of rollers, which lave not only a revolving motion in order to draw away the strips as fast as they are delivered by the condenser, but they also reciprocate longitudinally, and thereby roll thestrips into threads of a loose texture. The transmission of notion to these rubbingrollers has heretofore been accomplished by forming the hubs of the wheels with shoulders, so that they could revolve freely in their bearings, but were prevented from moving longitudinally. The spindle which passed through the hub was made of such section or provided with such means as would prevent it from revolving in the hub of the wheel, but would permit its longitudiual motion therein, as indicated in Figs. 2, 3, 4, and 5; but the limited surface exposed by this contrivance to the propelling force and the excessive pressure latter, being thus relieved of the driving-strain,

will therefore be much less subject to wear;

My invention consists in providing the wheels A A with clutch-prongs O O, which engage with another clutch, M, which is fastened securely to the spindle D. The points of contact between the prongs O O and the 'clutch M should be "as far from the center of revolution of D as practicable, because the greater that distance the less pressure is required between 0 O and M, and consequently the less wear and tear. The clutch-proh gs 0 O are made of such length that they will renain in contact with the clutch M, while the longitudinal motion of the spindle D is produced by the eccentric Z.

lt will be observed that an important result of my invention is the fact that the greater part of the wear and tear is removed from the spindle D, an expensive part of the apparatus, and is thrown upon the clutch-prongs 0 O and clutch M, which are conparatively inexpensve.

I do not claim as my invention any of the parts mentioned separately; but

What I claim is- In combination with the wheel A, rubbing'- -roller E, and spindle D of condenser-cards, the

clutch-prongs O O and clutch M, acting and operating substantially as and for the purpose set forth.

GEORGE MALLISON.
